PSPDFDigitalSignatureCoordinator

Objective-C


@interface PSPDFDigitalSignatureCoordinator : NSObject <PSPDFOverridable>

Swift

class DigitalSignatureCoordinator : NSObject, Overridable

The digital signature coordinator handles signing and presenting a digitally signed document. Signing a document with a certificate creates a readonly copy, as the file has to be completely re-written.

Note

Depending on your application logic you will want to choose where to store this new file. PSPDFKit suggests a randomized temporary folder + file name as default location.

Register your subclass via overrideClass:withClass: on the configuration object. Don’t instantiate an object of this class yourself.

-pathForDigitallySignedDocumentFromOriginalDocument:suggestedFileName:

Path that is used for storing the newly created document, which will be digitally signed.

Note

fileName is a suggestion based on the title of the original document, which can be used in the path. The path will be sanitized, and it will me made sure that the suffix is .pdf.

Declaration

Objective-C

- (nonnull NSString *)pathForDigitallySignedDocumentFromOriginalDocument:
                          (nonnull PSPDFDocument *)document
                                                       suggestedFileName:
                                                           (nonnull NSString *)
                                                               fileName;

Swift

func pathForDigitallySignedDocument(fromOriginalDocument document: Document, suggestedFileName fileName: String) -> String






-presentSignedDocument:showingPageIndex:withPresentationContext:

Present the digitally signed document, containing the signature on pageIndex.

Declaration

Objective-C

- (void)presentSignedDocument:(nonnull PSPDFDocument *)signedDocument
             showingPageIndex:(PSPDFPageIndex)pageIndex
      withPresentationContext:
          (nonnull id<PSPDFPresentationContext>)presentationContext;

Swift

func presentSignedDocument(_ signedDocument: Document, showingPageIndex pageIndex: PageIndex, with presentationContext: PresentationContext)

Parameters

`signedDocument`	The newly created document containing the digital signature.
`pageIndex`	The page index the digital signature is on. You can use this to scroll to this page when presenting the new document.
`presentationContext`	A presentation context that can be used to present the new document to. Usually the `PDFViewController` that initiated the digital signing process.






-configureSignatureAppearanceWithBuilder:document:signature:

Subclassing hook that can be used to configure the signature appearance.

Note

If an ink signature has lines set, the signatureGraphic will be preconfigured.

Declaration

Objective-C

- (void)
    configureSignatureAppearanceWithBuilder:
        (nonnull PSPDFSignatureAppearanceBuilder *)builder
                                   document:(nonnull PSPDFDocument *)document
                                  signature:(nonnull PSPDFSignatureContainer *)
                                                signature;

Swift

func configureSignatureAppearance(with builder: PSPDFSignatureAppearanceBuilder, document: Document, signature: SignatureContainer)
